PO322 if I remember correctly is something to do with your G28 sensor (Crank pickup) or engine speed sensor  ,

It is situated in front of your engine (between the radiator and the motor) to the right of your oil filter unit slightly lower

Possible Symptoms
•   Engine shuts off
•   Engine doesn't start
•   Speedometer inoperative

Possible Causes
•   Engine Speed Sensor (G28) loose
•   Engine Speed Sensor (G28) faulty

Possible Solutions
•   Check Engine Speed Sensor (G28)

Hope this helps

Crankshaft position sensor is a good place to start. Any competent mech should be able to o-scope the sensor to test it.

If the crank sensor were bad, the car wouldn't start... So maybe theres a short or grounding issue with the sensors wiring. I would check there first. CPS is definitely a good place to start though, check sensor connection as well.
